Description

The present invention relates to a first agent composition for hair dyeing or bleaching.

Generally, as a hair dye composition, a hair dye, a decoloring agent, a decoloring agent, a decoloring / decoloring agent and the like are known, and two or more kinds of agents are mixed at the time of use. The hair dye composition has at least two or more kinds of alkali agent and a first agent composition containing an oxidative dye depending on the application, and a second agent composition containing an oxidizer, and are mixed at the time of use. A hair dye composition is prepared and applied to the hair. The hair dye composition penetrates into the hair by opening the cuticle on the hair surface with an alkaline agent. The hair dye composition that penetrates into the hair oxidizes and decomposes the melanin pigment of the hair itself with an oxidizer to lighten the hair, or chemically reacts (oxidation polymerization) the oxidative dye in the hair to form the pigment and the hair. The hair is dyed by fixing it inside.

However, since the hair dye composition damages the hair by the contained alkali agent and oxidizing agent, the hair feels and feels down, such as “feeling dry”, “stiff”, “loss of gloss” and the like. In the prior art, in order to reduce damage to hair after hair dyeing, a method for reducing hair damage by including a so-called silicone compound such as silicone having a specific viscosity or modified silicone in the hair dye composition. Has been proposed (Patent Documents 1 and 2).

However, in the prior art, the damage reduction of hair after dyeing is still insufficient, and there is room for improvement. In addition, when trying to contain a silicone compound in the first agent composition containing an alkaline agent or an oxidative dye of the hair dye composition for the purpose of reducing damage to the hair after hair dyeing, the effect of the silicone compound that is difficult to emulsify The emulsified state becomes unstable, and the first agent composition will cause separation when exposed to high temperatures in a car used for transportation to the high temperature in summer or overseas. was there. Moreover, when it tried to contain a silicone compound in the 2nd agent composition containing the oxidizing agent of a hair dye composition, it had a bad influence on an oxidizing agent and the stability of the oxidizing agent might fall. Accordingly, an object of the present invention is to provide a first agent composition for hair dyeing or decoloration that does not cause a decrease in feel or texture of hair after dyeing and is stable even when stored for a long time under high temperature conditions.
